Continuing in Chevrolet and GMC’s twinning ways is a 19 percent increase in max torque over the old Duramax diesel engine, as well as the new air intake system complete with an exterior hood scoop. The new system not only provides cooler air to help the engine run better under heavy loads but also creates plenty of those extra ponies and units of twist.

The 2017 GMC Sierra HD will be available in regular, double cab and crew cab models, plus the Sierra Denali HD. If you’re looking for a tad more capability off road, the All Terrain HD will add 18-inch chrome aluminum wheels with all-terrain tires, Z71 suspension with Rancho twin-tube shocks and more.
